Definitions
- the present disclosure generally relates to support stands and, particularly, to a support stand for a flat-panel display monitor.
- Flat-panel display monitors such as liquid crystal display monitors, offer advantages over cathode ray tube displays such as reduced size, smaller weight, and better image quality.
- a viewing angle and height of a flat-panel display screen of the flat-panel display monitor can be adjusted without moving a support stand of the flat-panel display monitor because of its light weight.
- the support stand is generally detachable relative to the flat-panel display screen, so that it is convenient to package the support stand and the flat-panel display screen in a case for transportation.
- a typical support stand 100 commonly used for supporting a flat-panel display screen 200 includes a support bracket 102 , a pair of clamping members 103 rotatably attached to the flat-panel display screen 200 , a torsion spring 104 positioned between top ends of the clamping members 103 , and a latching member 105 fixed on a top end of the support bracket 102 .
- Lower ends of the clamping members 103 cooperatively define a clamping space (not labeled) to engage with the latching member 105 .
- an external force is applied on the top ends of the clamping members 103 to rotate the clamping members 103 towards each other such that the torsion spring is elastically deformed.
- the top ends of the clamping members 103 move towards each other, the lower ends of the clamping members 103 move away from each other so that the latching member 105 can be received in the clamping space.
- the external force is released such that the latching member 105 is clamped by the clamping members 103 by an elastic force created by the torsion spring 104 .
- the support bracket 102 When the support bracket 102 is to be detached from the flat-panel display screen 200 , an external force is applied on the top ends of the clamping members 103 until the latching member 105 is detached from the clamping members 103 .
- the elastic force created by the torsion spring 104 must be suffficient for the clamping members 103 to firmly clamp the latching member 105 , so that a large external force is usually required to assemble or disassemble the support bracket 102 to the clamping members 103 . Therefore, it is troublesome to assemble or disassemble the support stand 100 from the flat-panel display screen 200 .
- the torsion spring 104 must deform when the clamping members 103 clamp the latching member 105 , so the torsion spring 104 is easily fatigued. Furthermore, the clamping members 103 and the latching member 105 are easily damaged by an excess external force. Thus, a usage life of the support stand 100 is relatively short.

Abstract
Description
- 1. Technical Field
- The present disclosure generally relates to support stands and, particularly, to a support stand for a flat-panel display monitor.
- 2. Description of Related Art
- Flat-panel display monitors, such as liquid crystal display monitors, offer advantages over cathode ray tube displays such as reduced size, smaller weight, and better image quality. A viewing angle and height of a flat-panel display screen of the flat-panel display monitor can be adjusted without moving a support stand of the flat-panel display monitor because of its light weight. The support stand is generally detachable relative to the flat-panel display screen, so that it is convenient to package the support stand and the flat-panel display screen in a case for transportation.
- Referring to
FIG. 8 , atypical support stand 100 commonly used for supporting a flat-panel display screen 200 includes asupport bracket 102, a pair ofclamping members 103 rotatably attached to the flat-panel display screen 200, atorsion spring 104 positioned between top ends of theclamping members 103, and alatching member 105 fixed on a top end of thesupport bracket 102. Lower ends of the clampingmembers 103 cooperatively define a clamping space (not labeled) to engage with thelatching member 105. - In use, an external force is applied on the top ends of the
clamping members 103 to rotate theclamping members 103 towards each other such that the torsion spring is elastically deformed. When the top ends of the clampingmembers 103 move towards each other, the lower ends of the clampingmembers 103 move away from each other so that thelatching member 105 can be received in the clamping space. After thelatching member 105 is received in the clamping space, the external force is released such that thelatching member 105 is clamped by theclamping members 103 by an elastic force created by thetorsion spring 104. - When the
support bracket 102 is to be detached from the flat-panel display screen 200, an external force is applied on the top ends of theclamping members 103 until thelatching member 105 is detached from theclamping members 103. The elastic force created by thetorsion spring 104 must be suffficient for theclamping members 103 to firmly clamp thelatching member 105, so that a large external force is usually required to assemble or disassemble thesupport bracket 102 to theclamping members 103. Therefore, it is troublesome to assemble or disassemble the support stand 100 from the flat-panel display screen 200. In addition, thetorsion spring 104 must deform when theclamping members 103 clamp thelatching member 105, so thetorsion spring 104 is easily fatigued. Furthermore, theclamping members 103 and thelatching member 105 are easily damaged by an excess external force. Thus, a usage life of the support stand 100 is relatively short. - What is needed, therefore, is a support stand for a flat-panel display monitor that overcomes the limitations described.
- The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views, and all the views are schematic.

Theresilient piece 755 includes a pair of latching blocks 7551 extending from opposite sides of theresilient piece 755. Theresilient piece 755 is received in thehead 7511 and latched by the restricting members 7517 of thehead 7511. The latching blocks 7551 are tightly engaged in the receiving groove 7515 of thehead 7511 to prevent the latching ends 7531 of thehandle 753 from detaching from the receiving groove 7515. - Referring to
FIGS. 2 and 3 again, thehinge assembly 30 may be assembled as follows. The shaft portion 333 of the pivot shaft 33 passes (in order) through one of the restrictingmembers 37, one of thetab washers 393, one of thesupport walls 311 of the fixingbracket 31, twotab washers 393, therotatable member 35, twotab washers 393, theother support wall 311 of the fixingbracket 31, the remainingtab washer 393, the other restrictingmember 37, and theresilient washers 391. Thenut 95 engages with thethreads 331 of the shaft portion 333 of the pivot shaft 33. Thetabs 3931 of thetab washers 393 adjacent to thesupport walls 311 of the fixingbracket 31 are received in thepositioning holes 3115 of thesupport walls 311, and thetabs 3931 of thewasher module 39 adjacent to therotatable member 35 are received in thepositioning grooves 3513 of therotatable member 35. The restrictingportions 373 of the restrictingmembers 37 are respectively received in the restrictinggrooves 3113 of thesupport walls 311. The pivot shaft 33 is rotatable relative to the fixingbracket 31. Therotatable member 35 and the restrictingmembers 37 rotate with the pivot shaft 33. A rotation range of the pivot shaft 33 is restricted by the restrictinggrooves 3113 of the fixingbracket 31. - The assembled
hinge assembly 30 is partially received in the fixinggroove 11 of thedisplay screen 10. A plurality of threaded fasteners of thefasteners 90 pass through the mountingholes 3131 of the fixingwall 313 to fix thehinge assembly 30 to thedisplay screen 10. - Referring to
FIG. 4 , thedisplay screen 10 and thesupport structure 50 are connected by thehinge assembly 30. Thefirst latching module 353 of thehinge assembly 30 passes through the receivinghole 513 of thesupport housing 51 and is received in the assemblingchamber 531 of thesupport body 53. Themovable plate 3534 of thefirst latching module 353 abuts the latchingportion 5513 of thepositioning plate 551 of thesecond latching module 55. When an external force is applied on thefirst latching module 353, the latchingportion 5513 presses themovable plate 3534 downwards and compresses theelastic members 3533. Thus, themovable plate 3534 completely moves past the latchingportion 5513, and force created between the latchingportion 5513 and themovable plate 3534 is eliminated. Theelastic members 3533 return themovable plate 3534 to an original position, and the latchingportion 5513 is latched in the assemblingchamber 531. - Referring to
FIG. 7 , when thesupport structure 50 is to be detached from thedisplay screen 10, another external force is applied to the press-button 557 in the receivinghole 571 of thesupport structure 50 to compress theelastic member 553, and thepressing pole 555 moves downwards to contact themovable plate 3534. Theelastic members 3533 are compressed by themovable plate 3534. Once themovable plate 3534 is below the latchingportion 5513, thehinge assembly 30 is withdrawn from thesupport structure 50, so that thesupport structure 50 is conveniently detached from thedisplay screen 10. - The
elastic members 3533 and theelastic member 553 are only deformed in the process of assembling or disassembling thedisplay screen 10 and thesupport structure 50, so that theelastic members 3533 and theelastic member 553 have a relatively long usage life. In addition, thehinge assembly 30 is partially received in thesupport structure 50 when latched with thesupport structure 50, so that thesupport structure 50 is firmly connected to thedisplay screen 10 and not easily damaged by an excessive external force. Thus, a usage life of the support stand 20 is relatively long. Further, thehandle 753 and theresilient piece 755 are fixed to the threadedfastener 751, so that thesupport structure 50 can be rapidly detached from thebase member 70 when the threadedfastener 751 is loosened by thehandle 753. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
